This activity will allow students to measure, on their own, the parallax angle of a selected asteroid and its distance, within an accuracy of 5%, in just two nights by using modest amateur gear. Each one of those two observing nights will require a maximum of half an hour of imaging, split into two sessions about 5-6 hours apart.
Students will learn that an astronomical observational project requires research, planning and execution. Many topics should be properly known and understood in order to successfully perform this activity. Most likely, many students will finally understand that astronomy is one of the few areas where scientific knowledge contribution is still within the reach of serious amateurs.
